Tension Stiffening Effect of High Strength Concrete

This paper describes an experimental investigation on the effect of concrete strength on tension stiffening behavior. Total ten direct tension specimens were tested with concrete compressive strength range up to 900kg/$\textrm{cm}^2$. From the experimental program, it was observed that higher strength concrete specimens provides smaller crack spacings and less stiffening effect.
